Pay inequality refers to the disparity in earnings between different groups of people, often based on factors such as gender, race, or job type. For example, studies have shown that women, on average, earn less than men for the same work, a phenomenon often referred to as the gender pay gap. This inequality can also be seen across different racial and ethnic groups, where individuals from minority backgrounds may receive lower wages compared to their white counterparts. Addressing pay inequality is important for promoting fairness and ensuring that all workers receive equal compensation for their contributions.
